SIGNIFICANT INCIDENCE OF SPLENECTOMY: Asplenism concerns a significant number of subjects: in France 6,000 to 9,000 patients undergo splenectomy annually. More than half of these patients are adults.

FROM ASPLENIA TO SEVERE INFECTION: The most serious consequence of asplenia due to absence of the spleen, its resection or its functional failure is the risk of severe infection. RAPIDLY PROGRESSIVE SEPTICEMIA: It is estimated that the risk of death due to septicemia is 200 times higher in splectomized patients than in patients with a spleen. Death occurs within several days or even hours in most of the patients due to overwhelming post-splenectomy infection (OPSI). ⋯ In adults, morbidity is 0.9% and mortality 0.8%. PREVENTION OF RECURRENCE: Furthermore, in an asplenic subject or in a patient with a chronic disease threatening the spleen, the development of infectious episodes is an expression of evolving immunodepression, calling for preventive measures against recurrence. Anti-pneumococcal vaccination and antibiotic prophylaxis using penicillin V considerably reduces the incidence of pneumococcal infection in splenectomized subjects.
